Question

I pass a Date object to a method which calls date.getHours() or any other method such as date.getFullYear() and it throws an error "Can't execute code from a freed script". It seems that IE9 does not properly support date objects used by date picker.

I’m new to javascript/general coding and have had a problem which only seems to occur in IE9. I am warning everybody about this as I may have gone about solving it in completely the wrong way…

I tried various different things in an attempt to solve this problem, such as:

if (date.getHours()=="undefined") {
    var localDate = new Date(date);
    var hours = localDate.getHours();
    // etc 
}

I now have a solution (it may not be the best, but it does the job) and will post it below, however I would like to know if anybody else has encountered the same problem and how they have resolved it?

Answer 1

In my experience, the problem happens when the Date object you’ve got was constructed in a different window, such that since its construction that other window has been closed or reloaded with a new page.

The solution is to send object inter-window in some string form, reconstituting them as necessary in the destination context.

(It isn’t just Date instances of course; it’s any object type. Primitives don’t have the problem, if I recall.)
